Can Family Members Override a Power of Attorney?

Can a sibling or relative overrule the named agent? Usually not — but here’s what family can and can’t do.

When one person is named Power of Attorney, other relatives sometimes ask: can we override them? It’s a fair question — and the answer reassures good agents while giving worried families a real path when something is wrong.

The short answer: usually not

A validly named agent acts with the principal’s authority. Other family members — even close ones — generally cannot simply overrule the agent’s decisions or install themselves instead. Disagreeing with the agent, or being the oldest child, doesn’t grant authority. That’s by design: it keeps decisions clear and prevents chaos.

What family *can* do

That doesn’t mean relatives are powerless. When there’s genuine concern, they can:

  • Talk to the principal. If the principal still has capacity, they’re in charge and can direct or revoke the Power of Attorney themselves.
  • Ask for transparency. Reasonable questions and a look at the records often resolve worry — which is exactly why agents should keep good records.
  • Report suspected abuse. If an agent is exploiting the principal, family can report it to adult protective services and others. Know the red flags of financial abuse.
  • Petition a court. As a last resort, a court can review the agent’s conduct, remove an abusive agent, or appoint a guardian — see can a Power of Attorney be challenged.

Two lessons here

For agents: transparency and records prevent most family conflict before it starts. For families: you can’t override a valid agent on a whim, but you’re never without recourse if someone is truly being harmed.

Serving in a way that keeps the whole family confident is a skill — and the POA Caregiver Program helps you do exactly that.
